UHS-1 is pretty fast as well. It can do 50MB/s write with ECC and there is also UHS104 which is capable of 104MB/s. Again, plenty fast.

I can shoot 1080p on the UHS-1 card I have without problems.

Depends on the bit rate. You will not be able to write directly to flash with an uncompressed 24bit 1080P 60fps stream obviously. ;)

Even so writing a video stream has little random i/o so you can do up to 85% or so STR. Multiple AV streams are going to be far more taxing.

of course. But we are talking smartphone/tablet here. Not exactly random read write hogs.

When the hell is FIOS going to come to my area? Something besides Comcast and ATT Uverse, which is what I currently have. I use the term loosely, as I only actually have it intermittently throughout the day.

We got FIOS here last summer. It's great. :biggrin: 50/30. Can go up to 250/30 if I want to. No cap. That was my biggest fear, that there would be a cap. In fact there used to be one for the packages higher than 50 and they removed it.

Sure it's fast enough for video, but again we were talking about loading the entire OS onto the SD card, which just isnt going to perform well, OS operations DO require higher I/O, which SD cards just don't offer. At least not currently under $60/16GB which is way too expensive to be considered viable for most devices. if they want to make a profit anyway.

you got fibre, FIOS is specifically Verizon's fibre service. Which starts at 15/15 and goes up to 500/500 at least around here.

OS reads a lot more than it writes...transcend 64 gb up to 90MB/s is 39 bux on amazon.

Do you know what IOPS are...?

at this point you just sound like a total idiot, you really don't know what the hell you are talking about and it shows.

Yeah, and for it to run smoothly you need decent I/O, normal SD cards do NOT provide this, which is why eMMC is used for internal memory on phones, not SD cards.


unless you're trying to say Read and write speeds are all that matter, in which case LMFAO. Random I/O performance is needed for internal memory.
